Washington (CNN) - After three days of talks focused on halting Iran's uranium enrichment efforts broke down Sunday morning, Sen. Lindsey Graham said Congress would not wait for the next round of negotiations.

Graham said he intends to put forward a measure that would mandate more sanctions on Iran, aimed at forcing the Middle Eastern nation to dismantle its nuclear weapons program - a move that runs counter to the interim steps sought by the negotiating parties gathered in Geneva, Switzerland.

Washington (CNN) - Sen. Lindsey Graham played the role of reluctant warrior Sunday, telling “Fox News Sunday's” Chris Wallace that he doesn't want to hold up every nomination in the Senate over what happened in Benghazi, Libya. But, he said, until the administration allows the Senate to hear testimony from survivors of the attack on the U.S. diplomatic mission there, he’ll block the White House at every turn.

"I shouldn't have to do this," the South Carolina lawmaker said. "I shouldn't have to make these kinds of threats."

Sen. Lindsey Graham will appear on "CNN's The Situation Room" Tuesday at 5pm

WASHINGTON (CNN) - Senators John McCain and Lindsey Graham continued their all-out verbal assault on the Obama administration's handling of the Syria crisis, disparaging Saturday's U.S.-Russian agreement as "morally and strategically indefensible."

"It requires a willful suspension of disbelief to see this agreement as anything other than the start of a diplomatic blind alley," the senators said in a joint statement, "and the Obama administration is being led into it by Bashar Assad and Vladimir Putin."

(CNN) – Republican Sen. John McCain, who met with President Barack Obama on Monday, said the president would "seriously consider" sending weapons to the rebel forces in Syria on top of a military strike against the country's regime.

"That means providing them not only weapons but the kind of weapons they need: anti-armor and anti-air. AK-47s don't do very well against tanks, so we discussed that and that that would be a course of action that the president would seriously consider, I guess is the best way to describe it," the Arizona Republican said Tuesday on CNN's "New Day."
